English Holly (Ilex aquifolium), also known as European holly or Christmas holly, is mildly toxic to cats if ingested. While not usually causing a severe allergic reaction, holly leaves and berries contain saponins and other compounds that can irritate a cat’s digestive system.

This popular evergreen shrub is commonly found in gardens and used in holiday decorations.

Symptoms your cat may have

If a cat eats holly leaves or berries, it may experience gastrointestinal upset. Common signs include:

  • Vomiting
  • Diarrhea
  • Drooling
  • Smacking lips or pawing at the mouth
  • Loss of appetite
  • Lethargy

In rare cases of a large ingestion, symptoms could progress to tremorsseizures, or coma. Punctures from the sharp leaf spines may cause irritation in the mouth.

Potential diagnosis your Vet may give

If you suspect your cat has eaten English Holly, contact your veterinarian. They will likely recommend the following steps:

  1. Perform a thorough physical exam to assess your cat’s condition
  2. If recent ingestion, induce vomiting or administer activated charcoal to reduce absorption of toxins
  3. Provide supportive care with fluid therapy and medication to control vomiting
  4. Monitor blood work and organ function in severe cases
  5. Provide a bland diet as the digestive system recovers

Your vet can provide the best course of treatment based on the amount ingested and your cat’s symptoms. Quick treatment usually results in a good prognosis.

History of the English Holly

English Holly has a long history of use in Europe, dating back to ancient Celtic and Roman traditions. Seen as a symbol of eternal life and fertility, holly was used in pagan winter solstice celebrations. As Christianity spread, the prickly leaves came to represent Jesus’ crown of thorns and the red berries his blood, and holly became associated with Christmas. The wood has also been used to make walking sticks, birdcages, and chess pieces.

Today, holly is a popular ornamental plant and is still featured in Christmas decor, though precautions should be taken to keep pets from nibbling the alluring sprigs.
